Foldable parasol

Abstract

The present invention relates to a foldable parasol in which rotation of a second arm portion is restricted by a rotation locking means, thereby allowing the second arm portion to be unfolded and fixed in a straight form with a first arm portion, or the rotation restriction of the second arm portion is released to allow the second arm portion to rotate relative to the first arm portion and be folded. More specifically, the second arm portion connected to a canopy fabric can be selectively folded to the left or right side of the first arm portion according to the fastening position of a hinge shaft in the rotation locking means. As an operating rod of the rotation locking means descends due to the tension of a wire, a support portion of a locking piece moves downward toward the second arm portion and supports the rear surface of a second connection piece. Accordingly, the second arm portion can be unfolded and fixed in a straight form with the first arm portion, while also preventing the second connection piece from separating from a first connection piece due to the load applied to the second arm portion.

Description

Folding parasol

[0001] The present invention relates to a parasol that blocks sunlight and provides shade to a user, and to a foldable parasol that can minimize the volume of the parasol by folding an arm portion that supports a sunshade.

[0002]

[0003] In general, a parasol is a device that provides shade to users by blocking strong sunlight outdoors. It is especially used in summer when the temperature is high to block strong sunlight and provide shade, thereby blocking the heat caused by sunlight and preventing skin burns and sunstroke or heatstroke caused by ultraviolet rays. It is widely used for leisure activities such as picnics, swimming, and fishing.

[0004] These parasols are mostly composed of a folding awning and a support pole, and are installed by fixing the support pole to the ground or a structure. As the sun moves over time and the angle of incidence of sunlight gradually changes, the user changes the resting position in response, or changes the angle and position of the awning and support pole to match the angle of incidence of sunlight.

[0005] Therefore, when using a conventional parasol, the user had to change his / her position according to the angle of incidence of sunlight, which caused the user to be unable to rest comfortably for a long time and had to move periodically, which was a problem.

[0006] Additionally, there was a problem in that the arm of the parasol could not be folded or separated, so the space taken up by the parasol could not be reduced when not in use.

[0007]

[0008] The folding parasol of the present invention is connected by a rotation locking means to a first arm portion extending from a support and a second arm portion to which a sunshade is connected, and the second arm portion is fixed in a primary form with the first arm portion or folded in one direction of the first arm portion according to the operation of the rotation locking means, thereby solving the problem of a conventional parasol in that the arm portion cannot be folded or rotated, so that it cannot respond to changes in the position of the sun, and the parasol cannot reduce the space occupied by the parasol when it is not in use.

[0009] In addition, another purpose is to provide a parasol in which the wire can be easily replaced while the rotation locking means is attached to the arm.

[0010]

[0011] Therefore, in order to achieve the above purpose, the folding parasol of the present invention is a folding parasol in which a second arm is rotatably connected to a first arm of the parasol by a rotation locking means, and the rotation of the second arm is suppressed by the rotation locking means so that the first arm and the second arm are spread out and fixed in a straight shape, or the second arm is rotatable so that the second arm is rotated in one direction of the first arm and folded.

[0012] The above rotation locking means is,

[0013] A first connecting piece formed at one end of the first arm portion, having a first through hole through which a parasol wire passes, and a hinge axis connected to one end thereof;

[0014] A second connecting piece arranged at one end of the second arm portion so that the front faces the first connecting piece, is fastened to the hinge axis and is rotatably connected to one end of the first connecting piece, and has a second through hole formed therein through which a wire passes;

[0015] An operating rod that is arranged to be able to move up and down on a first connecting piece by an elastic spring, a wire passing through the first hole passes through the inside, and is lowered by downward pressure according to the tension of the wire; and

[0016] A fastening member is fastened to the upper portion of the above-mentioned operating rod, a support member is formed at one end of the fastening member that is bent downward, and moves up and down together with the above-mentioned operating rod, and when the above-mentioned operating rod is lowered, the support member descends to the second arm member in front of the second connecting member to support the back surface of the second connecting member, and the second connecting member is caught on the support member to suppress rotation of the second arm member that is arranged in a line with the first arm member.

[0017] In addition, the present invention is a folding parasol in which a second arm is rotatably connected to a first arm of a parasol by a rotation locking means, and the rotation locking means inhibits the rotation of the second arm so that the first arm and the second arm are spread out and fixed in a straight shape, or the second arm is rotatably made so that the second arm is rotated in one direction of the first arm so that the second arm is folded, wherein the rotation locking means is

[0018] A first connecting piece formed at one end of the first arm portion, having a first through hole through which a parasol wire passes, and a hinge axis connected to one end thereof;

[0019] A second connecting piece arranged at one end of the second arm portion so that the front faces the first connecting piece, is fastened to the hinge axis and is rotatably connected to one end of the first connecting piece, and has a second through hole formed therein through which a wire passes;

[0020] An operating rod that is arranged to be able to move up and down on a first connecting piece by an elastic spring, a wire passing through the first hole passes through the inside, and is lowered by downward pressure according to the tension of the wire; and

[0021] A fastening member is fastened to the upper portion of the operating rod, a support member that moves up and down integrally with the operating rod and has a support groove at the lower portion is formed by being bent downward from the front portion of the fastening member, and when the operating rod is lowered, the support member is lowered to the second arm member in front of the second connecting member, so that the second arm member is inserted into the support groove, and a locking member is included that prevents rotation of the second arm member that is arranged in a line with the first arm member by catching the side of the second arm member in the support groove.

[0022] In addition, the present invention is characterized in that a fixing rod is formed on the upper portion of the first connecting piece, the rear end of the fastening portion is fastened to the fixing rod so as to be able to move up and down, and the fastening portion is fastened to the fixing rod and the operating rod so that the locking piece is supported so as not to rotate.

[0023]

[0024] The present invention has the effect of allowing the second arm portion connected to the sunshade of the parasol to be selectively folded to the left or right of the first arm portion depending on the fastening position of the hinge axis of the rotation locking means, thereby enabling the appropriate use of the space occupied by the parasol.

[0025] In addition, as the operating rod of the rotation locking means descends due to the tension of the wire, the support portion of the locking piece descends to the second arm portion, and the support portion blocks and supports the back surface of the second connecting piece, so that not only is the second arm portion spread out and fixed in a straight line with the first arm portion, but there is also a remarkable effect of preventing the first connecting piece and the second connecting piece from being separated due to the load of the second arm portion.

[0026] In addition, the present invention has the effect of suppressing rotation of the second arm portion by inserting the second arm portion into the support groove of the support portion and supporting it so that it does not rotate when the support portion is lowered to the second arm portion while the first arm portion and the second arm portion are spread out in a straight line shape.

[0027] In addition, the present invention can be implemented so that a wire passes through the operating rod while the operating rod of the rotary locking means is connected to the first connecting piece, and has the effect of allowing easy replacement of the wire without separating the operating rod from the first connecting piece.

[0043]

[0044] As illustrated in FIGS. 1 to 3, the arm portion (20) applied to the parasol of the present invention is divided into a first arm portion (21) that is bent and extended in one direction from the upper portion of the support member (10), and a second arm portion (22) to which the awning cloth (2) of the parasol is connected, and the first arm portion (21) and the second arm portion (22) are rotatably or foldably connected by a rotation locking means (100). In addition, the first arm portion (21) and the second arm portion (22) can be connected so as to be inclined upward as they go from the support member (10) toward the awning cloth (2).

[0045] The first arm (21) can be bent in one direction from the upper part of the support (10), and a wire (1) connecting the winding means and the support joint passes through the hollow interior, and the second arm (22) is separated from the first arm (21) and a awning (2) is connected or supported at the end.

[0046] And the first arm portion (21) and the second arm portion (22) are connected by a rotation locking means (100), and the wire (1) of the parasol passes through the inside.

[0047] The rotation locking means (100) of the present invention comprises: a first connecting piece (110) formed at one end of a first arm portion (21); a second connecting piece (120) arranged at one end of a second arm portion (22) so that the front face thereof faces the first connecting piece (110) and is rotatably coupled to one end of the first connecting piece (110) by a hinge shaft (130); an operating rod (140) provided to be movable up and down to the first connecting piece (110) by an elastic spring (150), a wire (1) of a parasol passing therethrough, and descending by downward pressure according to tension generated when the wire (1) is wound; And a fastening member (161) is fastened to the upper part of the operating rod (140), a support member (162) that is bent downward is formed at one end of the fastening member (161), and moves up and down together with the operating rod (140), and when the operating rod (140) is lowered, the support member (162) is lowered to the second arm member (22) in front of the second connecting member (120) to support the back surface of the second connecting member (120), and the second connecting member (120) is caught on the support member (162) to suppress rotation of the second arm member (22) that is arranged in a line with the first arm member (21).

[0048] The first connecting piece (110) is connected to one end of the first arm portion (21), and a first through hole (110a) through which a wire (1) passes is formed to communicate with the first arm portion (21), and an upper support piece (111) having a first connecting hole (111a), a second connecting hole (111b), and a third connecting hole (111c) is formed at the upper portion, and a lower support piece (112) facing the upper support piece (111) vertically is formed at the lower portion, and the upper support piece (111) and the lower support piece (112) protrude forward of the first arm portion (21).

[0049] The upper support piece (111) and the lower support piece (112) may be formed integrally with the first connecting piece (110) and may be detachably coupled to the upper and lower parts of the first connecting piece (110).

[0050] In addition, a fourth connecting hole (112a) and a fifth connecting hole (112b) corresponding to the first connecting hole (111a) and the second connecting hole (111b) of the upper supporting piece (111) are formed in the lower supporting piece (112) of the first connecting piece (110), and the hinge shaft (130) can be inserted into the first connecting hole (111a) and the fourth connecting hole (112a) or selectively inserted into the second connecting hole (111b) and the fifth connecting hole (112b).

[0051] And, a third connecting hole (111c) is formed in the central portion of the upper support piece (111), that is, between the first connecting hole (111a) and the second connecting hole (111b), and an operating rod (140) to be described later is connected to the third connecting hole (111c) so as to be able to move up and down.

[0052] At one end of the second arm portion (22), a second connecting piece (120) is formed that is connected to the first connecting piece (110) by a hinge axis (130).

[0053] The second connecting piece (120) is arranged so that the front side faces the first connecting piece (110) when the first arm portion (21) and the second arm portion (22) are spread out in a straight line, and a second opening (120a) corresponding to the first opening (110a) is formed, and a first connecting hole (121a) and a second connecting hole (121b) corresponding to the first connecting hole (111a) and the second connecting hole (111b) are formed on the left and right sides of the front side.

[0054] The first connecting hole (121a) and the second connecting hole (121b) are formed in a tube shape and are formed in a vertical direction on the front surface of the second connecting piece (120), and a hinge shaft (130) is inserted into the first connecting hole (111a) or the second connecting hole (111b) of the first connecting piece (110), thereby allowing the second connecting piece (120) to be rotatably coupled to the first connecting piece (110).

[0055] And, in the central portion of the second connecting piece (120), a second hole (120a) corresponding to the first hole (110a) is formed, and a wire (1) passes through the inside of the second hole (120a).

[0056] The first connecting hole (121a) and the second connecting hole (121b) may be formed in the shape of a hollow tube or ring, and it is preferable that the inner diameter be formed to a size corresponding to the inner diameter of the first connecting hole (111a) and the second connecting hole (111b).

[0057] The connection of the first connecting piece (110) and the second connecting piece (120) is such that the first connecting hole (121a) and the second connecting hole (121b) of the second connecting piece (120) are arranged between the upper support piece (111) and the lower support piece (112) of the first connecting piece (110), and the first connecting hole (111a) and the first connecting hole (121a) are vertically connected on the left side of the first connecting piece (110), and the second connecting hole (111b) and the second connecting hole (121b) are vertically connected on the right side of the first connecting piece (110).

[0058] And when the hinge shaft (130) is inserted into the first connecting hole (111a) and the first connecting port (121a), the first connecting piece (110) and the second connecting piece (120) are combined so that the second arm part (22) can rotate to the left of the first arm part (21), and conversely, when the hinge shaft (130) is inserted into the second connecting hole (111b) and the second connecting port (121b), the first connecting piece (110) and the second connecting piece (120) are combined so that the second arm part (22) can rotate to the right of the first arm part (21). The above hinge axis (130) is formed with a head portion having a radius larger than the radius of the first connecting hole (111a) and the second connecting hole (111b), and thus the head portion is supported by the upper support piece (111) and does not fall out of the first connecting hole (111a) and the second connecting hole (111b).

[0059] The present invention has the effect of being able to selectively and easily fasten a hinge shaft (130) to the left or right side of a first connecting piece (110), and easily change the rotational direction or folding direction of a second arm portion (22) depending on the selection of the position at which the hinge shaft (130) is fastened to the first connecting piece (110).

[0060] Meanwhile, an operating rod (140) is fastened to the first connecting piece (110) to descend by the downward pressure according to the tension of the wire (1) and to rise by the elastic restoring force of the elastic spring (150), and a locking piece (160) is fastened to the operating rod (140) to suppress the rotation of the second connecting piece (120) and thereby suppress the rotation of the second arm portion (22).

[0061] The above-mentioned operating rod (140) is configured to be vertically movably coupled to a third connecting hole (111c) formed in an upper support piece (111) of a first connecting piece (110), and includes a head portion (141) formed with a larger radius than the third connecting hole (111c); a body portion (142) inserted into the third connecting hole (111c) and vertically movably coupled to the first connecting piece (110), and having an elastic spring (150) and a fastening portion (161) of a locking piece (160) fastened to the upper portion, the elastic spring (150) being seated on the upper portion of the first connecting piece (110), and the fastening portion (161) of the locking piece (160) being arranged between the elastic spring (150) and the head portion (141); and a wire support portion (143) formed at the lower part of the body portion (142), through which the wire (1) passes, and through which the downward pressure of the wire (1) is transmitted.

[0062] In addition, the locking piece (160) is formed in a roughly “ㄱ” shape, and a fastening part (161) formed in a horizontal plane is fastened to the operating rod (140), and a support part (162) is formed in the front part of the fastening part (161) that is bent downward and extended to a predetermined length, and moves up and down as one with the operating rod (140), and when the operating rod (140) is lowered, the support part (162) is lowered to the second arm part (22) in front of the second connecting piece (120) to support the back surface of the second connecting piece (120), and the second connecting piece (120) is caught on the support part (162) to suppress the rotation of the second arm part (22).

[0063] A through hole is formed in the fastening portion (161) of the above locking member (160) through which the body portion (142) of the operating rod (140) can pass, and the wire support portion (143) can be formed in the shape of a tube with an interior that is perforated in the front-back direction, and a wire (1) drawn out from the first arm portion (21) through the first through hole (110a) passes through the interior of the wire support portion (143), and the wire (1) can be supported on the bottom surface of the wire support portion (143).

[0064] And when the wire (1) of the parasol is wound, the wire (1) is pulled and becomes taut, generating tension, and as the wire (1) descends according to the tension of the wire (1), the wire support (143) is pressed downwards, and the operating rod (140) descends, and as the operating rod (140) descends, the support (162) of the locking piece (160) descends to the second arm (22) in front of the second connecting piece (120) to support the back of the second connecting piece (120), and as a result, the second connecting piece (120) is caught on the support (162) and rotation is suppressed.

[0065] That is, when the wire (1) is wound and tension is generated while the first arm (21) and the second arm (22) are spread out in a straight line, the operating rod (140) descends, the support (162) of the locking piece (160) descends to the second arm (22) in front of the second connecting piece (120), and the back surface of the second connecting piece (120) is supported and blocked by the support (162), so that the rotation of the second connecting piece (120) is suppressed, and thus the rotation of the second arm (22) is suppressed.

[0066] In addition, since the support member (162) supports or presses the back surface of the second connecting piece (120), there is an effect of preventing the first connecting piece (110) and the second connecting piece (120) from being separated.

[0067] In addition, the operating rod (140) is fastened to the upper support piece (111) of the first connecting piece (110), supported by a wire (1), and moves up and down by an elastic spring (150) disposed between the upper support piece (111) and the fastening piece, and when the tension of the wire (1) disappears, it rises again by the elastic restoring force of the elastic spring (150), as shown in FIGS. 4 and 5, and as a result, the support part (162) rises to the upper side of the second connecting piece (120), thereby releasing the rotational inhibition of the second connecting piece (120), and the second arm part (22) becomes rotatable.

[0068] When the second connecting piece (120) is fixed so as not to rotate by the support member (162) of the above locking piece (160), the operating rod (140) can be fixed so as not to rotate due to the tension of the outer ear and the engagement of the support member (162) and the second connecting piece (120), and more preferably, at least one fixing rod (113) for preventing rotation of the operating rod (140) is formed on the upper support member (111) of the first connecting piece (110).

[0069] The above-mentioned fixed rod (113) is formed with at least one fixed rod (113) of a predetermined length on the upper support piece (111), and the rear end of the fastening portion (161) of the locking piece (160) is connected to the fixed rod (113) so as to be able to move up and down.

[0070] The above-mentioned fixed rod (113) may be formed on the rear side of the third connecting hole (111c) to which the operating rod (140) is coupled in the upper support piece (111), and as shown in FIG. 6, at least two of them may be formed on the rear side of the first connecting hole (111a) and the second connecting hole (111b), and may be formed to be arranged in a triangular shape with the operating rod (140) or / and the third connecting hole (111c).

[0071] The fastening portion (161) of the above locking piece (160) is fastened to the fixing rod (113) and the operating rod (140), thereby preventing rotation of the first connecting piece (110).

[0072] When the above-mentioned fixed rod (113) is formed with at least two spaced apart pieces on the first connecting piece (110), the locking piece (160) can be stably connected to the first connecting piece (110) and the second connecting piece (120) can be stably supported so that it does not rotate.

[0073] In addition, a support nut can be fastened to the above-mentioned fixed rod (113), and the locking piece (160) is supported by the support nut without coming off from the fixed rod (113), and when the fixed rod (113) rises, it gets caught on the support nut, thereby limiting the rising height.

[0074] In addition, the support portion (162) of the locking piece (160) has a semicircular support groove (162a) formed at the lower end corresponding to the radius of the second arm portion (22).

[0075] When the operating rod (140) and the locking piece (160) are lowered by the downward pressure according to the tension of the wire (1), the support groove (162a) surrounds the upper part and the left and right sides of the second arm part (22), and the side of the second arm part (22) is blocked by the support groove (162a), thereby suppressing the rotation of the second arm part (22).

[0076] That is, when the operating rod (140) is lowered, the support part (162) is lowered to the second arm part (22) in front of the second connecting piece (120), so that the second arm part (22) is inserted into the support groove (162a), and the side of the second arm part (22) is caught in the support groove (162a), so that the rotation of the second arm part (22) arranged in a line with the first arm part (21) is suppressed.

[0077] Accordingly, the present invention has the effect of doubly suppressing the rotation of the second arm portion (22) by having the second connecting piece (120) caught on the support portion (162) and fixed so as not to rotate when the first arm portion (21) and the second arm portion (22) are spread out in a straight line shape, and also having the second arm portion (22) inserted into the support groove (162a) of the support portion (162) and supported on the side.

[0078]

[0079] In addition, as shown in FIG. 7, the locking piece (160) may be formed so that the fastening portion (161) and the support portion (162) are spread at an angle of 90°, but may be formed so that they are spread at an angle of between 70° and 120°.

[0080] That is, when the support portion (162) is opened at an angle of 70° to 90° with respect to the fastening portion (161), the lower part of the support portion (162) can press the rear surface of the second connecting piece (120), and when it is separated at an angle of 90° to 12° with respect to the fastening portion (161), the support portion (162) can not only easily descend to the front of the second connecting piece (120), but also descend so as to be in contact with the incline of the second arm portion (22) perpendicularly, so that the second arm portion (22) can easily be introduced into the support groove (162a), and also the support portion (162) can be raised and lowered without being caught on the rear surface of the second connecting piece (120).

[0081] Accordingly, in the present invention, when the first arm portion (21) and the second arm portion (22) are spread out in a straight line shape, when the wire (1) is wound and tension of the wire (1) is generated, downward pressure according to the tension of the wire (1) is transmitted to the operating rod (140), so that the operating rod (140) and the locking piece (160) descend, and the support portion (162) of the locking piece (160) descends to the second arm portion (22) in front of the second connecting piece (120) to support the back surface of the second connecting piece (120), and the second arm portion (22) is introduced into the support groove (162a) of the support portion (162) so that the side surface of the second arm portion (22) is blocked, thereby suppressing the rotation of the second connecting piece (120) and the second arm portion (22).

[0082] And when the wire (1) is released and the tension is eliminated, the locking piece (160) rises and the support part (162) rises above the second connecting piece (120), thereby allowing the second connecting piece (120) and the second arm part (22) to rotate.

[0083] In addition, as illustrated in FIG. 8, the outer support member (143) may be formed in a “∩” shape with an open bottom, and a roller (144) for supporting the wire (1) may be provided inside, thereby allowing the wire (1) to pass through the inside of the wire support member (143) while the operating rod (140) is connected to the first connecting piece (110), and there is an effect that the wire (1) can be easily replaced.

[0084] The above operating rod (140) is separated into a head (141), a body (142), and a wire support (143), and while separated from each other, an elastic spring (150) and a locking piece (160) are fastened to the body (142), and then the head (141) is fastened to the upper end of the body (142) that protrudes upward from the locking piece (160).

[0085] In addition, the operating rod (140) may be formed integrally with the head (141) and the body (142), and a wire support (143) may be detachably coupled to the lower part of the body (142).

[0086] And the body part (142) to which the elastic spring (150) and the locking piece (160) are connected is inserted into the third connecting hole (111c) of the first connecting piece (110) and connected to the fixing rod (113), whereby the elastic spring (150) is secured to the upper portion of the upper support piece (111). And the wire support piece (143) is connected to the lower portion of the body part (142) which is arranged between the upper support piece (111) and the lower support piece (112), and the wire (1) is placed inside the wire support piece (143), and then the roller (144) is connected to the wire support piece (143).

[0087] Accordingly, the present invention has a remarkable effect in that it can easily suppress the rotation of the second arm portion (22) in the first arm portion (21), and when the rotation of the second arm portion (22) is suppressed, it can prevent the second connecting piece (120) from being separated from the first connecting piece (110) by the weight of the second arm portion (22), and the wire (1) can be easily replaced even when the rotation locking means (100) is coupled to the first arm portion (21) and the second arm portion (22).
